Asaphiscus wheeleri Trilobite Gallery

Asaphiscus wheeleri trilobite fossil from Utah


Asaphiscus Trilobite Facts and Information:

Asaphiscus wheeleri is a plain looking trilobite from the Cambrian. It is one of the more abundant trilobites in the Wheeler Shale. Their body shape and mouth parts suggest Asaphiscus, as well as the rest of the order, was a particle feeder that walked along the sea floor.

Asaphiscus trilobites are mostly found with the free cheeks missing. The average size for an Asaphiscus is around 1 to 2 inches. Large ones are around 2.5", and HUGE ones are around 3". The largest COMPLETE one I've seen is one I've found (image below), it's at 2 7/8" (73mm).

Phylum: Arthropoda
Class: Trilobita
Order: Ptychopariida
Family: Asaphiscidae
Genus:Asaphiscus
Species: Wheeleri
Locality Information:
Asaphiscus wheeleri can be found in the Cambrian of North America (Utah and Nevada), and in Australia.

Asaphiscus Wheeleri Trilobite Fossil


This is the largest complete Asaphiscus trilobite I've seen. It is also interesting, where its shell is REALLY thin and is wavy. The means it probably just molted and died, the exoskeleton didn't have time to harden (kind of like a soft shell crab).

Age: Cambrian
Formation: Wheeler Shale
